Can you tell me what the changes are in this new release? There is no change log available in the news archive.

#29223

It seems the binary PDF document data is corrupted. Usually that happens by a HTTP transfer, when an undesired character encoding conversion is applied to a binary PDF document.

In PD4ML JSP taglib byte[] result PDF data is sent 2 ways:
[language=java:3bo2snuj]sr.setContentLength(result.length);
ServletOutputStream sos = sr.getOutputStream();
if ( this.getEncoding() != null && this.getEncoding().equals(“default”) ) {
sos.write(result);
} else {
sos.print( new String( result, “ISO8859_1” ) );
}
sos.close();[/language:3bo2snuj]

Try both in your Tomcat app.

Another more rare reason of such corruption is a replacement of UNIX-style new line characters with Win-style double chars. The problem may happen, but it is quite unlikely to face with in web scenarios.

#26818

Hi,

I’m having trouble with the styling of a PDF I generate from HTML.
When I save the HTML as a file and open it in a browser, it looks good . On the other hand, The PDF that I generate from this HTML string doesn’t look good (mostly in terms of fonts, padding, alignment etc.).
I believe that I’m not using any special styling in my HTML page.
Where can be a good starting point to find out what’s causing my PDF not to look good?

Thanks,
Ziv

Hi,

I’m attaching a sample code of a png rendering of an html page.

I tested the example code on a Stand alone J2SE program and its rendering the page into PNG24 just great.

Then I took the exactly same code, and putted inside a Sptring MVC controller in my Jetty server, and it render the page but into PDF, ignoring outputFormat(PD4Constants.PNG24);

Is there another way that I can force the render to be made on PNG?

Both program are using the same jar 381

Thanks for your time!
Juan

#29235

Hi Juan

I tried what you said and it also happened to me.
Right now, I am testing the tool and I will be needing the configuration that you mentioned.

Did you reached a solution?

Cheers

#29236

Hi,

I was using the non pro versions, that seems to not support outputFormat change

WARNING: outputFormat() takes no effect in non-Pro PD4ML versions
version: PD4ML 381 (eval)

I will download the PRO trial and test it.

Thanks!

#29241

Did you override the default max heap size with -Xmx???m JVM command line parameter? The default value as a rule is not sufficient for HTML rendering.

#29237

You are right: to perform HTML->Image conversion you need PD4ML Pro (or any derived volume license library).

As I see in your code sample there is pd4ml.enableDebugInfo() call. It should report to STDOUT/server’s log the following message:

[language=java:1mhs96fk]if ( debug && !isPro() ) {
System.err.println( “WARNING: outputFormat() takes no effect in non-Pro PD4ML versions” );
}[/language:1mhs96fk]

#29242

yes, it is set to 256m

#29243

HTML rendering (especially of that big docs) is a resource consuming task. We recommend to set at least 512m, but 1gig is better.

It does not mean JVM immediately allocates the memory – it only defines a limit for peak cases.

#26820

Dear friends,

I have developed html file which contains data with image file. Then i have used pd4ml for converting Html file to Pdf.
Pdf file is successfully created with data only. i.e. Images are not displaying. But html file is displaying on browser with image also.

Please give me the suggestion.

Thanking You,

Regards
Satyaprasad

#29238

The following info is a good starting point to debug:

#29239

Hi,

In which area, we will write pd4ml.enableDebugInfo();
